IMPRovr-.MENT 1N MEAT-ayunas.

The Schedule referred to in these Letters Patent. and making part of the name.

I, GEORGEA P. TREULIEB, of the city of Baltimore, in the State of Maryland, have invented a new and` useful Improvement in Meat-Cutters;' and do hereby describe the same. V

Nature and Objects of the Invention. 'My'invention consists in a novel device for raising the block toward the knives as it wears away in the operation.

General Description with Reference lto the Drawings.

Intlre accompanying drawingsl Figure 1 is a plan or top view'of the apparatus, one-half of the block remoyed, in supports.

Figine 2 is an elevation thereof.

Figure 3 is a perspective view of the sliding frame `supporting the worm, hereinafter described;

Like letters of reference indicate simi'ar parts in the diierent figures.V

A represents the block, resting on rollers a a a, which, running -iu bearings b b b, rigidly attached to the horizontal worm-wheel B, allow the block A to revolve freely -during the cutting-operation.

C O are upright posts, between which the block moves, and by which it is held in position.

I) is a pinion, adapted to slide up and down in the j vertical driving-shaft E, and held, by a set-screw, F,' in any position to which it may be adjusted. Its teeth mesh into the horizontal gear-wheel or rim G, which is attached to the block A byscrews c c, or other means, for the purpose of communicating rotary motion thereto.

lhe shaft E turns in a step, H.

The elevating-screw I is rigidly attached to the horizontallworrn-whecl B, and moves in a female screw, U, which is formed in the bed-plate of the machine.

K represents the endless screw or worm, which gears with the horizontal wheel B.

L L M fig. 3, are guides, on which the frame of the worm K slides, respectively, up or down. vClhey may be extended to 4any desired length, to accommodate the position of the worm to the respective position of the worm-wheel B.

' N O, tig. 3, are side bars of the frame, the former of which, being bent upward, and extending inward of the machine, as shown in iig. 2, rests on the surface of the wheel B, thus supporting the worm in proper.po sition.

order to showits P P are slides, moving on the outer sides of the I guide M, while the slide P'moves between the two gnides'LL.

R It arethe cross-bars of the frame, forming, in

their extension between the side bars N and O, the bearings S S, for the axis '.l, fig. 1, of the worm.

Opera-tion.

In order to raise the block A, forward motion is given -to the worm K by means of a crank or key applied to its axis T. The worm K, gripingintoV the teeth of the gear-wheel B, turns the latter, and thus causes the screw I, rigidly attached to it, to rise,and

lift it, and, with it, the block A. The pinion D is then y brought into suitablepositiomand, after being rigidly attached to the vertical shaft E, by means of set-screw F, motion is given to the shaft E, by which the block is turned. While thus raising the apparatus, the side bar N'of the frame, resting on the surface of the gear-whecllB, follows the upward movement of the latter, and, being rigidly attached to the cross-bars R R, forming the `bearings of the axis T of the worm,

cause the latter to rise in the same proportion, being held in its horizontal position by means of the guides L L and slide I" at one side, and by means of the guide M and slides P Plat the other side.

The guides L L M may be made of any desired or suitable length, so as to allow the worm to follow the upward movement of the apparatus to anydesired extent.

Claims.

I claim, as my invention- 1. In combination with the worm K, the frame N O R R, bearings S S, guides L L M, and slides P I P', all constructed and arranged substantially as and for the purposes specified. f

.2. The combination and arrangement of the block A, rollers a a a, worm-wheel B, worm K, its frame N
